Locationing Software

The main function of the Wi-Fi Tag is to aid the determination of the location of the assets or personnel to which the tag is attached. This is accomplished in several ways - one of which is by the tag transmitting packets at pre-defined intervals in pre-configured channels and transmission patterns. These packets, and information pertaining to them, are forwarded to an appropriate location infrastructure, which may be located anywhere in the IP network. By using the received signal strength in those packets, location engines residing in the server compute the position and location of the tags. Another method is to have the tags scan for Wi-Fi Access Points in the vicinity and report their location along with the signal strength measurements of their transmissions to the location server. Here, there is no dependency on the Wi-Fi infrastructure to determine the location. The WiSeMote Location Management software offers the ability to compute the location of tags using the information reported by them. The enterprise product is delivered in three variants:

CCX

WiSeMote tags can be configured to operate in a standard 'blink' mode conforming to Cisco's CCX specifications. Cisco infrastructure components and locationing software would need to be used to complete the solution. The tags may be configured to operate in the 2.4 or 5 GHz bands, with a motion sensor enabling different blink rates when stationary and in motion. Push button and choke point based wake-up is also available.

SAP

RPX-SAP is Redpine's complete locationing solution that utilizes existing Wi-Fi infrastructure. Any third-party Access Points may be used. Locationing is carried out by Redpine's Location Engine, with tags communicating the signal strengths of the APs they see. A site survey is required for accuracy of locationing. Based on the site survey, the locationing infrastructure may be augmented either with more standard APs or with Redpine SuperMote devices. Redpine's asset management software or third party applications may be used.

NAP

There are situations where a simple locationing solution offering a broad indication of the location of an asset is sufficient. The RPX-NAP solution intended for such cases. The solution works with a standard access point infrastructure with no requirement of multiple AP visibility through the premises or a site survey. The simplified locationing software provides an indication of which AP the tag is in proximity to - sufficient, for instance, to indicate that a specified asset is on the "7th floor East Wing" or "the dining area". Tags connect to a configured SSID and communicate signal strengths of the APs they see to the server, as in the case of a full locationing solution with standard APs. The NAP software framework provides the vicinity indication to application software, including Redpine's Asset Management software.
